PROBLEM TO BE SOLVED: To provide an operation control device of a water jet propulsion boat in which required turnability can be acquired even when throttle operation is not carried out and a driver can get a natural feeling of steering. SOLUTION: The operation control device of a water jet propulsion boat 1 which injects water stream rearward and sails by the reaction, includes a turnable revolution number maintaining means 17 which keeps the revolution number of an engine at a turnable revolution number such that the turning force can be obtained when the throttle operation amount is minimized, and a means for controlling the revolution number at a low speed which can control the engine revolution number not to be larger than the turnable revolution number.
